Hammer Strength Stability Ball

One of the strongest balls in the industry, The LifeFitness Hammer Strength Stability Ball is a must for any strength training routine. Its superior durability means it can withstand loads up to 2000 lbs without bursting—an important feature when you are working out with heavy weights. Unlike your typical yoga ball, this product will challenge the balance, stability, and strength of your strongest athletes and clients. This workout ball inflates up to 75 cm, which is appropriate for most ball exercises.
